Gaillardia plant named ‘Baltoryell’

ABSTRACT

A new and distinct cultivar of  Gaillardia  plant named ‘Baltoryell’, characterized by its yellow-colored ray florets, light green disc florets and vigorous, upright, and mounded growth habit.

Latin name of genus and species of plant claimed: Gaillardia pulchella.

Variety denomination: ‘Baltoryell’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Gaillardia plant botanically known as Gaillardia pulchella and hereinafter referred to by the cultivar name ‘Baltoryell’.

The new cultivar originated as the product of the open-pollination, in November 1999, of the proprietary breeding selection designated ‘NCT-137-2’ (not patented) with a mix of pollen from plants grown from Thompson & Morgan double Gaillardia mix (not patented). The new Gaillardia was discovered and selected as a single flowering plant within the progeny of the above stated open-pollination during October 2000 at Arroyo Grande, Calif.

Asexual reproduction of the new cultivar by terminal stem cuttings taken since November 1999 at Arroyo Grande, Calif. and West Chicago, Ill. has demonstrated that the new cultivar reproduces true to type, with all the characteristics as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

It was repeatedly found that the cultivar of the present invention:

-   -   1. Forms yellow-colored ray florets and light green-colored disc         florets, and     -   2. Exhibits a vigorous, upright, and mounded plant habit.

‘Baltoryell’ has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment such as temperature, light intensity, and day length without, however, any variation in genotype.

‘Baltoryell’ is distinguished from its female parent primarily in inflorescence color.

Of the Gaillardia cultivars known to the inventor, the most similar to ‘Baltoryell’ is ‘Sundance’ (not patented). However, in side-by-side comparisons, plants of the new cultivar differ from plants of ‘Sundance’ primarily in inflorescence color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical inflorescence and foliage characteristics of the new cultivar. The plants were grown for 12 weeks in a greenhouse at West Chicago, Ill.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of colors described herein is The R.H.S Colour Chart of The Royal Horticultural Society, London, England 1995 edition, except where general terms of ordinary significance are used. The color values were determined on May 21, 2003 in West Chicago, Ill. The readings were taken between 10:00 and 11:45 a.m. under natural daylight conditions. The plants were produced from cuttings taken from stock plants and were grown in a double polycarbonate-covered greenhouse in West Chicago, Ill. under conditions comparable to those used in commercial practice. The plants were grown in 10 cm pots while utilizing a soilless growth medium. Greenhouse temperatures were maintained at approximately 65°-75° F. (18°-24° C.) during the day and approximately 60° 65° F. (15°-18° C.) during the night. Greenhouse light levels of 5,000-8,000 footcandles were maintained during the day. Plants were pinched at three weeks after planting. The following measurements and descriptions were taken at 12 weeks after planting of rooted cuttings.
